The California Highway Patrol is rolling out a 12-hour statewide crackdown on impaired driving, with a Maximum Enforcement Period set from 6 PM tomorrow through 6 AM next Sunday. Drivers across California should be ready for a long night of extra officers on highways and surface streets, plus temporary sobriety checkpoints, roving DUI saturation patrols and more traffic stops than usual.
As reported by Action News Now, the CHP says it will deploy all uniformed CHP personnel for traffic enforcement statewide, regardless of rank. The timing is no accident. The agency is targeting the start of a busy summer weekend when, it says, more people are on the road and more of them are out late.
What officers will do
During a Maximum Enforcement Period, CHP officers typically mix standard traffic stops, DUI saturation patrols and temporary checkpoints to pull impaired drivers off the road before crashes happen. Public notices from the agency show that prior operations have led to hundreds of DUI arrests and thousands of enforcement contacts statewide. In an October 2025 release, CHP said crashes related to impairment account for more than 800 fatal collisions on average each year in California. The agency has used this same playbook for holiday periods and late-night traffic details.
Why the agency says it matters
Impaired driving remains one of the leading causes of deadly wrecks. Federal numbers show alcohol-impaired crashes have made up roughly 30% of U.S. traffic fatalities in recent years, according to the National Highway Traffic Safety Administration. State crash tools and reports from the California Office of Traffic Safety and UC Berkeley’s Transportation Injury Mapping System highlight thousands of injury crashes each year that involve alcohol or drugs, which is the core justification CHP gives for these high-visibility sweeps. TIMS provides the underlying crash data for California.
How to avoid a ticket and stay safe
The CHP and its traffic safety partners keep the advice simple: if you plan to drink, do not plan to drive. That means lining up a sober driver, using rideshare or public transit, or staying overnight where you are. The agency also urges people who see a suspected impaired driver to call 9-1-1 and be ready with a vehicle description, license plate number and direction of travel, in line with CHP guidance.
This Maximum Enforcement Period is one of several traffic operations CHP runs through summer and over holiday weekends, so drivers should treat the overnight window as higher risk and expect delays near checkpoints. If you absolutely have to be out, law enforcement has the same standing recommendation it has pushed for years: do not drive impaired, unless you feel like ending your night in the back of a patrol car.
